UVA rays are less commonly associated with skin cancer, but that does not mean they are safe.
It wasn’t until recently that sunscreens began to protect consumers against both UVA and UVB rays.
Most products protected against UVB rays because they were the rays most commonly associated with sunburn.
Now, broad spectrum sunscreens are available that protect against UVA and UVB rays.
But they can only provide so much protection.
But there are limitations to the protection, and tanning beds are one of those limitations.
But these organizations do not advise that you use sunscreen in a tanning bed.
They simply advise avoiding tanning beds and tanning lamps completely.
Premature Aging from Tanning Bed Use
Beyond increasing cancer risk, tanning beds also cause premature aging.
Unfortunately, human skin isn’t very forgiving when damaged by UV exposure.

It is a common myth that getting a “base tan” before vacation will protect you from sunburn.

Avoid using a tanning bed entirely.
Exposure to the UVA and UVB rays that they emit increases your risk of skin cancer and premature aging.
Some people feel that getting a “base tan” before sun exposure can help protect their skin.
However, it is not effective against sunburn, and it is doing more damage than good.
